[Supervised administration of Alzheimer's patients using information communication technology].

Drug adherence is central to the treatment of dementia, which might reduce compliance due to memory loss, particularly among home-based patients with dementia. In order to improve drug adherence, we suggest the efficient and effective supervised administration by use of information communication technology(ICT). ICT makes face-to-face real-time communication possible, and it also enables picture sharing. Therefore, it might be useful to apply ICT to controlling and supervising medication for patients with dementia to improve drug adherence. Accordingly, we enrolled patients who were supposed to take a newly prescribed anti-dementia patch containing the choline esterase inhibitor rivastigmine(Rivastach®)and investigated the effect of ICT-based intervention for drug adherence, emotional change, and cognitive change, utilizing Skype, a free communication software program. Scheduled Skype interventions increased drug adherence ratio, levels of subjective satisfaction, and instrumental activities of daily living(IADL). Furthermore, we can provide patients and their caregivers with a feeling of safety through regular bidirectional communication, as patients can easily consult medical staff regarding the adverse effects of newly prescribed drugs. Instead of frequent visits to their primary physicians, ICT-based communications can be used as a substitute for supervision of medication, given the availability of the telecommunication system. By directly connecting the medical institution to the home, we expect that this ICT-based system will expand into the geriatric care field, including the care of elderly individuals living alone.

[Support for the medication monitoring of patients with alzheimer's dementia by the interactive care system using IT].

In our laboratory, we draw up research aims to improve medication compliance in patients with dementia by video phone, and we have intervened in the cases of 3 patients to date. In this study, we focused on patients who are using a rivastigmine patch for Alzheimer' disease, which can be confirmed by video phone, to examine its efficacy. Specifically, by monitoring the effects of the treatment, skin side effects, of skin and usability for patients and caregivers, we monitor the dosing schedule to prevent interruption of self-medication, with the aim of improving compliance and treatment efficacy. We also consider methods of intervention for increasing the persistence rate of the rivastigmine patch and quality of life(QOL)by using the effectiveness of the video phone to focus on the symptoms of skin side effects. In addition, we examine the interventions that reduce the care burden and anxiety of caregivers by listening during the regular intervention.

A morphometric study of the vagus nerve in amyotropic lateral sclerosis with circulatory collapse.

Amyotrophic lateral sclerosis (ALS) shows peculiar abnormalities of the autonomic nervous system, including sympathetic hyperactivity, which might result in sudden death. In general, the sympathetic hyperactivity could be caused by disruption of vagal inhibition. Our objective was to evaluate the vagus nerve morphometrically in autopsy cases of ALS with sympathetic hyperactivity and circulatory collapse (CC). We investigated 10 autopsied ALS patients, six of whom had exhibited autonomic storms or CC. We also examined 10 patients without ALS as controls, and one patient with Guillain-Barré syndrome (GBS) who died from CC, for comparison. After obtaining the visceral branch of the left vagus nerve at necropsy, we analyzed the density of the myelinated and unmyelinated fibers, and the fiber diameter distribution for each fiber. Results showed that the densities of both myelinated and unmyelinated fibers in ALS patients with or without CC were not significantly different from those in control patients. In contrast, the GBS patient showed marked reduction in the whole myelinated and large unmyelinated fiber density. In conclusion, the autonomic storms or CC due to sympathetic hyperactivity in ALS could not be ascribed to the deafferentation of the baroreflex, and more central neural pathophysiology should be investigated.

A case of Marinesco-Sjögren syndrome: MRI observations of skeletal muscles, bone metabolism, and treatment with testosterone and risedronate.

Marinesco-Sjögren syndrome (MSS) is a rare autosomal recessive disorder characterized by cerebellar ataxia, congenital cataracts, mental retardation, primary hypogonadism, skeletal abnormalities and myopathy, and patients with MSS are considered to be at risk of falls and bone fractures. We report a patient with MSS who received testosterone replacement therapy and risedronate administration. Muscle strength and the MRI features of the skeletal muscles were not changed, but low bone mass was improved by these treatments, and improvement has continued after risedronate treatment alone. This case suggests that treatment of MSS-related low bone mass using bisphosphonates is likely beneficial.

Distinct characteristics of amyloid deposits in early- and late-onset transthyretin Val30Met familial amyloid polyneuropathy.

Late-onset transthyretin Val30Met-associated familial amyloid polyneuropathy (FAP ATTR Val30Met) cases unrelated to endemic foci in Japan show different clinicopathological features from the conventional early-onset cases in endemic foci. We compared the characteristics of amyloid deposits in early-onset FAP ATTR Val30Met cases in endemic foci and late-onset cases in non-endemic areas. Amyloid deposits in three early-onset cases from endemic foci and five late-onset cases from non-endemic areas were systematically examined post-mortem. Amyloid deposits in early-onset cases were highly congophilic and showed strong apple-green birefringence with Congo red staining and had long, parallel fibrils in most organs. On the other hand, those in late-onset cases were generally weakly congophilic and showed faint apple-green birefringence with Congo red staining and had short, haphazard fibrils. In the renal glomus and adrenal gland of early-onset cases, the characteristics of amyloid deposits were similar to those observed in late-onset cases. Analysis of cardiac amyloid using surface enhanced desorption/ionization time-of-flight mass spectrometry indicated that most transthyretin (TTR) was variant in early-onset cases, while more than half was composed of wild-type TTR in late-onset cases. Although characteristics of amyloid deposits may differ among individual organs of respective cases, especially in early-onset cases, the pattern was distinct between early- and late-onset cases. Amyloid deposition in late-onset cases may be similar to that observed in senile systemic amyloidosis with wild-type TTR deposition, suggesting that aging may play an important role in these cases.

A Japanese case of autoimmune autonomic ganglionopathy (AAG) and a review of AAG cases in Japan.

A 29-year-old woman presented with acute, pure autonomic (both sympathetic and parasympathetic) failure and positive antibody to ganglionic nicotinic acetylcholine receptor; the diagnosis was autoimmune autonomic ganglionopathy (AAG). She had typical symptoms of AAG, although the patient also had coughing episodes and psychiatric symptoms, which are not typical of AAG in Western countries but are common in AAG cases in Japan. In a review of the Japanese literature, 29 cases of AAG had been reported. AAG patients in Japan were younger and more male predominant than in Western countries. Of the patients in these 29 cases, 10 (34.5%) had coughing episodes and 12 (41.4%) had psychiatric symptoms.

Depression in patients with subacute myelo-optico-neuropathy (SMON).

OBJECTIVE: We investigated the psychiatric disorders in subacute myelo-optico-neuropathy (SMON) patients by structured interview. The prevalence of major depressive disorder in SMON patients was estimated by structured interview and using Beck's depression inventory (BDI) questionnaires. MATERIALS AND METHODS: Psychiatric conditions were evaluated in 26 SMON patients (9 males, 17 females, mean age 70.7 years) living in Kyoto prefecture through a structured interview given by psychiatrists. BDI questionnaires and clinical symptoms of SMON were investigated in 106 patients, ranging from 51 to 91 years in age (mean, 73.5) with SMON patients living in Kinki area. BDI questionnaires were obtained from 92 age-matched aged healthy people, ranging from 57 to 91 years in age (mean, 75.8), living in Kyoto city. RESULTS: Among the psychiatric disorders in SMON patients, the prevalence of major depressive disorder and suicidal ideation significantly increased during the period of clioquinol intake and four patients (15.4%) out of 26 SMON patients still suffer from major depressive disorder. The prevalence of major depressive disorder in SMON patients was estimated at 15.1% (16/106) and this percentage was about seven times as frequent as in the age-matched aged healthy people (2.2%; 2/92). In female SMON patients, the degree of the depressive states was significantly correlated with the severe degree of dysesthesia of the lower extremities, and it was inversely correlated with the duration of SMON disease and the total scores of the Barthel index. CONCLUSION: This is the first report that shows the prevalence of major depressive disorder in SMON patients at present, which was seven times more frequent than age-matched aged healthy persons.
